    * Sub- miniature series 3 solenoid values (General Valve Corporation, Fairfield, NJ). When the electronically-controlled 6 volt valves are over-driven at 9 volts, the total response time … … 5-15 psi, the valves proved to be reliable in releasing volumes ranging from 12 -120 pL.
  • Third-generation security robot
    The gun accumulator is monitored by a MicroSwitch model 242PC1500 electronic pressure transducer, and maintained at a constant pressure of 120 psi by a second solenoid valve connected to a 150-psi air bottle externally mounted on the rear body trunk. The main air bottle is automatically recharged by a small 12 - volt reciprocating compressor mounted in the robot's base, and monitored by a Data Instruments model EA200 pressure transducer. The rotating barrel assembly is powered by a miniature PortEscap gearhead motor with an armature-driven phase …
